……………………… reaction obeys the expresison `t_(1//2) = 1//ka` in chemical kinetics.A. `1`B. `0`C. `3`D. `2` |
Answer» Correct Answer - D `t_(1//2) = (1)/(Ka)` for second order reactions. `t_(1//2) = (1)/(K(a)) rArr t_(1//2) prop (1)/([a]^(1))` `rArr t_(1//2) prop [a]^(-1)` Also, `t_(1//2) prop [a]^(1-n)` `[a]^(n-1) = [a]^(-1) rArr 1 - n = -1` `n = 2` |
